:This invention relates to oven ,door construction, and an object is to provide an oven door and a door frame assembled in a novel relationship and includingan improved device for controlling the opening and closing of the door and t0 limit extent-of movement of the doortoward open position.

`Another object ofthe invention is to provide Van oven door having novel pivotal sup- Vportsand a spring retarder connected to one jof lthe pivotal 'supports and cooperating `therewith to control movement of the door Vtoward open'position. f

4Other'objects will appear from the `forllowing description, 4.reference being made to Fig. Vl'ris'an inside elevation of the oven door and frame.

Fig.2 is a sectional view approximately on the line `2 2 vof Fig. 1'. v j j Fig 3 is a v'front elevation of the part of the oven wall and door frame and door.

Fig. 4 isa detail view showing means for stopping and supporting the oven door in approximately horizontal open position.

The front wall 1 of the oven has an opening therethrough which is surrounded by a rigid door frame 2. This rigid door frame 2 is integrally or rigidly supported inwardly from the inner surface of the wall 1 by an inwardly extending flange 3. This provides a construction in which the door 4 can be received within the opening in the wall 1 and f, in such position is surrounded by the flange 3 and seats against the frame 2. The door 4 has on one lower corner a laterallyT projecting hinge 5. The hinge 5 projects through a hole 6 in the flange 3 under a stop abutment lug 7 rigid with the wall 1 and having an inclined surface 8 which is designed and adapted to be engaged by the face 9 of a lug 10 when the door is swung outwardly and downwardly to approximately `horizontal position and thereby support the door.

, A projection 11 extends laterally from the opposite lower corner of the door in axial alinement with the projection 5 and forms a hinge for the opposite endof the door. An arm 12 extending angularly from the proj ection 11 is connected by a pivot V13 with a fork 14 on the lower end of a rod 15. The upper end of the rod- 15 extends for sliding movements through a guide bracket 16 rigid with Vthe wall Y1 adjacent to the flange 3. vThe bracket 16 is attached to the wall 1 by a removable screw 17, the threaded end of which is received in a thickened portion 18 of the wall 1 so that no part of the screw is eX- application filed April 8,'

posed on the outside of the wall. A spring Q19 fencircles the rod 15 and has .its lower end abutting against the fork 12 and its'upper end against the bracket 16, thus tending to hold the door 4 closed but .yieldingto permit Vthe door to open.

That part of the wall oftheoven that cooperates with the projection 11 comprises a -removable panel 20 fitting in an opening provided therefor at the corner of the door opening. The lower end of the flange 3 at this sideofthe door opening terminates above the projection 11 so that when the panel 2O is not in place there is suliicient room to permit Vthe projection 11 and the arm'12 to bepassed laterally through the opening that is finally covered bysaid panel 20 and properly located :tocooperate with the projection 5 to function as a hinge .for the lowerredge of the door. When these parts are properly.

ilocated the :panel 20 is'secured in position by `-engaginga projection 21 at the upper end" of Ythe panel against the inside of the adjacent fportion of the wall 1 and, by fastening the lower end of the panel to the-wall bymeans n Yof alscrew 22. This screwV 22 is removable and passes through the marginal portion of -the wallland into an adjacent thickened por- :tion ofthe panel 2O so that no part ofsaid VscrewiseXposed on Vthe outside. A vertical flangef23 on the edge of the panel 2O that is `adjacent .zto the flange 3 is formed, with a (V. La)

jection 11 and arm 12 when the panel 20 is removed.

When the door is assembled in this manner the hinge projections 5 and 11 are pivotally connected with the oven wall so as to permit the door to be opened and closed. The door is received within the opening bordered by the iiange 3 and is thereby held from endwise movement in either direction, but may be freely opened and closed.

Tliepresent subject matter is divided from my prior application Serial No. 297,178, filed August 3, 1928.

The construction, arrangement and relationship of the parts may be varied within equivalent limits without departure from the nature and principle of the invention. I do not restrict myself in any unessential respects, but what claim and desire to secure by Letters Patent is 1. In a stove, a wall having a door opening, flanges extending inwardly along the margins of the door opening and having holes therethrough at the lower corners of the door opening, a door seating frame rigid with said flanges, a door mounted in said opening for movement to and from position against said frame, a projection rigid with one lower corner of said door extending laterally through one of said holes beyond said opening and engaging the inner side of said wall and forming a pivot for said corner of said door, a rigid abutment engaged by said projection when the door is swung outwardly and downwardly, a removable panel at the opposite corner of said opening, a projection from said door in axial alinement with said first projection engaging the inner side of said panel and cooperating with said first projection to permit the door to be swung to open and closed positions, and means for holding said panel in position.

2. In a stove, a wall having a door opening, iianges extending inwardly along the margins of the door opening and having holes therethrough at the lower corners of the door opening, a door seating frame rigid with said flanges, a door mounted in said opening for movement to and from position against said frame, a projection rigid with one lower corner of said door extending laterally through one of said holes beyond said opening and engaging the inner side of said wall and forming a pivot for said corner of said door, a rigid abutment engaged by said projection when the door is swung outwardly and downwardly, a removable panel at the opposite corner of said opening, a projection on the adjacent corner of said door in axial alineinent with said first projection and engaging the inner side of said panel and forming a pivot cooperating with said first named pivot and permitting the door to be swung to open and to closed positions, a dei vice extending outwardly through said wall and extending into said panel and holding said panel in position, and resilient means cooperating with said second projection resisting the movement of the door to open position and assisting in closing the door.

3. In a stove, an oven wall having a door opening therethrough, a rigid door frame surrounding said opening and having an opening through one of the sides thereof at one of its lower corners, a panel for closing said corner opening in said frame and having a hole extending outwardly and terminating short of the outer surface of said panel, a fastener extending outwardly through said wall and engaging in said hole and having its outer portion entirely covered by said panel and clamping said panel against said wall, and a projection on the opposite end of of said panel from said fastener extending against the inner side of said wall.

4c. ln a stove, an oven wall having an opening therethrough, a rigid door frame around said opening and having an opening through one side thereof at one of the lower corners of said frame, a panel for closing said opening and having a thickened portion at its lower end seated against the outer surface of the wall, a fastener extending outwardly through said wall and terminating in and being enclosed by said thickened portion of said panel and fastening said panel in position, and a projection on the upper end of said panel extending against the inner surface of said wall and cooperating with said fastener to hold said panel rigidly in position.
